PATENT NIPPLE-GRIP FOR BICYCLE-WHEELS.

srncirrcA'rroiv forming art of Letters Patent no. 648,13l5, dated April 24, 1966.

Application filed August 14,1897. seen No. 648,215. (No model.)

citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Nipple -Grip's for Bicycle- Wheels; and I do hereby declare tl1e'follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains'to make and use the same, reference being had to the accompanying drawings, andto figures part of this specification.

My invention relates to improvements in nipple-grips for adjusting the tension of the wire spokes of bicycle-wheels in the operation of truing the same; and it consists of a. disk having its outer edge provided with an annular flange, the flange having formed therein a series of radial grooves graduated in size and adapted for turning engagement with the nipples upon the spokes of a bicycle wheel,

of reference marked thereon,-which form a the halves of the disk on each side of the spokev constituting. two levers operating in opposite directions upon the nipple. 1

Iwill now describe in detail the manner in which I have carried out my invention and then claim what I believe to be novel; In the drawings, Figure 1 shows my improved grip in operative engagement with one of the nipples of a bicycle-wheel. Fig. 2 is a central transverse section of my improved grip in the position shown in Fig. 1, and Fig.

3 is a perspective view of my improved grip.'

Referring to the drawings, 1 is the disk, preferably of steel and about one-sixteenth of an inch in thickness. Around its outer edge is the annular flange 2, preferably at right angles.

walls, the inner end of each groove being preferably rounded, as shown. It will be seen that the grooves 4E and 8, 5 and 9, Sand 10; and 7 and 11 are placed diametrically opposite each other. I

In operation the grip is so adjusted in position, "as seen in Figs. 1 and 2', that the nipple 12 will fit snugly in one of the grooves, as 8, and the wire spoke 13, whichds' in screw-threaded engagement with the nipple 12, will lie loosely in the opposite groove 4:. In this position the grip can be readily turned-by the hand to re v olve the nipple, and therebyincrease or de= crease thetension of the wire spoke 13 in the operation of truing the wheel..

It will be seen that thehalves of the disk on each'side ofv the spoke constitute two levers opera ting in opposite directions upon the nip ple to.turn the same, which makes the manipulation exceedingly easy, and efflcient;

The outer periphery of the grip,as will be I seen, is preferably convex in cross-section, so

that when the grip is in operative position it can barely touch the inner convex polished surface of the rim 14:, so that the chances of marring the rim-surface are very slight.

It will be seen that. my improved grip is adapted for. use with all-sized nipples, is-

quickly placed in operative position upon the nipple and spoke, has no parts to become detached or broken,and is extremely economical in construction and light and compact in form.
